方法：对收治的56例角膜栗刺异物患者的发病、诊断及治疗情况进行回顾性总结，分析发病时间、视力、手术方法及手术疗效。

结果：男性患者多于女性，多数患者年龄<50岁。未发现复合外伤性白内障患者。82%患者可直接在门诊裂隙灯下取出栗刺。18%患者需要住院在显微镜下取出栗刺。治疗后视力好于治疗前，差异有显著意义(P<0.05)。

结论：角膜栗刺外伤表现多样，不同类型的栗刺采用不同的方法可提高疗效，大大降低患者住院率和治疗费用。

METHODS: Totally 56 cases with chestnut thorn foreign bodies in corneal were studied retrospectively, and we analyzed how long foreign bodies had been in the eyes and where they lay, the visual acuity and etc. Different operative treatments and operation effects were also analyzed.

RESULTS: Males were more than females in patients. Most patients were less than 50 years old. No composite traumatic cataract was found. 82% patients were removed by the slit-lamp in outpatient department, 18% patients were removed the foreign bodies under operating microscope in inpatient department. Visual acuity after treating was better than that before treating. There are significant difference in both groups(P<0.05).

CONCLUSION: Chestnut thorn foreign bodies in corneal were variable. It could to improve the therapeutic effect and reduce the cost of medical care that different foreign body types use different method.
